Answer 1

Hi, It looks like the screenshot isn’t opening on my end. Could you please resend it again?

Also, are you installing the driver from your computer manufacturer’s website? May I know your PC’s make and model?

Answer 2

Follow these steps to fix the “No audio output device is installed” issue.

1. Check that an audio device/driver exists

• Select Start and type Device Manager, then open it.
• Expand Sound, video and game controllers.
• If no audio device is listed, or it shows a warning icon, continue with driver reinstall.

2. Update the audio driver

• In Device Manager, under Sound, video and game controllers, right‑click the audio device (for example, Realtek, Intel SST, or similar).
• Select Update driver.
• Select Search automatically for drivers.
• Follow the on‑screen instructions and then restart the PC.

If Windows reports the best driver is already installed or the problem persists, continue.

3. Reinstall the audio driver

• In Device Manager, expand Sound, video and game controllers.
• Right‑click the audio device and select Uninstall device.
• If shown, check Delete the driver software for this device (or Attempt to remove the driver for this device), then select Uninstall.
• Restart the PC. Windows will attempt to reinstall the audio driver automatically.

4. Use the generic Windows audio driver If reinstalling does not help:

• Open Device Manager again and expand Sound, video and game controllers.
• Right‑click the audio device and select Update driver.
• Select Browse my computer for drivers.
• Select Let me pick from a list of device drivers on my computer.
• Choose High Definition Audio Device (the generic Windows driver), select Next, and complete the wizard.

5. If audio broke after a Windows Update

• Open Device Manager → expand Sound, video and game controllers.
• Right‑click the audio device → Properties.
• Go to the Driver tab and select Roll Back Driver (if available), then follow the prompts.

6. If no device appears at all

• Visit the PC or motherboard manufacturer’s support site and download the latest audio driver for the exact model and Windows version, then install it and restart.

If, after these steps, the device still does not appear or audio still shows “No audio output device is installed,” the issue may be hardware‑related and require OEM support.
